Flatworms (Platyhelminthes):
To this class of animals belong the unpopular planaria which sometimes massively reproduce in aquariums and then can become a disturbing pest. They mostly lead a hidden existence and appear only at night. After using a planaria trap many people are surprised how many flatworms were present in their aquariums! Since chemical means against planaria have mostly unwanted side effects, the JBL planaria trap is a very good alternative without harmful side effects!

Flatworms in marine water:
Flatworms in marine water can look very beautiful, such as slugs. But they can also cause problems for corals, when they increase alarmingly and infest the corals. There are Turbellaria which, extremely well camouflaged, even can’t be found on a closer look. This also includes e.g. the Acropora-eating flatworm which can infest stony corals and lead to serious damage. Through an iodine bath of the affected coral outside the aquarium (2 ml Betaisodona/l) the Turbellaria will be paralysed and can be flushed away with a strong water jet. The wrasse Pseudocheilinus hexataenia is considered as the recommended natural enemy of choice, as it can even recognise clutches of worms to eat them.

No, because the bristle worms are much thicker than the thin tube and can’t contract enough.

Why don’t the planaria crawl into the trap?

Planaria are choosy eaters. It’s best to find out what their favourite food is and use this food as bait for the trap. We have found NovoTab and PlanktonPur give very satisfying results.

Does the trap need to be filled with water?

Yes, before you close the trap with the white lid, it needs to be completely filled with water so that it can sink and the food can attract the planaria.

Why shouldn’t the trap be placed flat on the substrate?

At the entrance of the trap there is a thin tube. The entrance needs to have contact with the floor so that the planaria, coming from the substrate, can reach the bait in the trap. For this purpose you can use the enclosed suction pad alone or together with the cord. If the small tube is aligned in a 45° angle to the flour, like a small ramp, the flatworms are easily able to reach the trap. Another possibility is, to dig in the trap, so that the thin tube just can reach the floor.
